TIE-PLATE.

SPECIFICATION forming part of Letters Patent No. 754,025, dated March 8, 1904,

Application ii1ed November 16, 1903. Serial No. 181,278. (No model.)

To all z/wm t may concern:

Be it known that I, AUGUSTE ST. PIERRE, a subject of the King of Great Britain, residing at Rivires Trois Pistoles, county of Temiscouata, Province of Quebec, Canada, have invented certain new and useful Improvements in Tie-Plates; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to tie-plates such as used in railway construction at the rail-joints.

The object of the invention is to provide a tie-plate of such construction as will reduce to a minimum the shock which is occasioned by the wheels of the train passing over the joint.

The invention consists in the construction and combination of parts to be more fully described hereinafter, and denitely set forth in the claims.

In the drawings, which fully illustrate my invention, Figure l is substantially a side elevation of a rail-joint which is provided with my tie-plate. Fig. Q-'is a plan of sucha joint. Fig. 3 is a perspective, on a somewhat enlarged scale, showing my tie-plate.

Throughout the drawings and specification the same numerals of reference denote like parts. A

Referring more particularly to the parts, l and 2 represent the adjacent extremities of two adjoining rails. These extremities 1 and 2 of the rails substantially abut and are. connected in the usual manner by means 0f fishplates 3. Beneath the joint is provided a tieplate 4, which rests upon the ties 5 beneath the joint in the usual manner. This tie-plate is preferably of substantially the form shown, consisting of an elongated substantially rectangular plate having a body 6 of increased width and reduced portions 7 or extremities therebeyond. Upon its opposite edges the body 6 of the aforesaid tie-plate 4 vis provided with notches or recesses 8, and these notches are located so that they will lie, respectively, on opposite sides of the joint 9, as shown.

The reduced extremities 7 of the tie-plate are similarly provided with notches or recesses 10, which notches are not placed opposite to each other, but preferably disposed somewhat out of alinement with each other, as shown. These notches 8 and 10 are intended for the purpose of receiving spikes l1, which are .driven into the upper faces of the ties 5 in the usual manner, so that their heads 12 will clamp the flanges 14 of the rails. Upon the upper side the tie-plate is completely covered by a liner or cushion l5, which is preferably composed of a thick sheet of rubber or similar material adapted to absorb a shock. The ends of the rails rest directly upon this cushion in the manner indicated in such manner that the ends of the rails at the joints are supported in an elastic manner and so that the cushion which the plate constitutes will absorb the shock of the passing car, as will be readily understood.

It should be observed that the notches which are formed in the edges of the tie-plate are also Vformed in the edges of the cushion 15,

and it should appear, too, that the said cushion 15 conforms substantially in outline throughout to that of the tie-plate.

In the manner described a very efficient tieplate is formed which adords means for absorbing the shock and materially reducing the amount of vibration and movement of the parts incident to the passing of the trains.

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myselfrto the precise form shown, for many of the ydetails may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. As a new article of manufacture, a tieplate consisting of an elongated substantially rectangular plate having a member of elastic material superposed upon the same, said plate and said member having notches in the edges thereof and conforming substantially in outline to each other.

2. As a new article of manufacture, a tie- 5 plate consisting of a metallic plate substantially of elongated rectangular form, said tieplate having reduced extremities, and a rubber cushion superposed upon said metallic plate and conforming substantially in outline 10 thereto, said tie-plate having notches in the edges thereof adapted to receive spikes.

3. A rail-joint, comprising, in combination,

abutting rails, fish-plates disposed on the side thereof, a cushion consisting of a Hat elastic member disposed beneath the flanges of said 15 rails, a metallic plate beneath said cushion, said metallic plate having notches in the edges thereof adapted to receive spikes.

In witness whereof I have hereunto set my hand in the presence of two Witnesses.

AUGUSTE ST. PIERRE.
